valve lash? piston slap? detonation? pinging? could be any of em. check the condition of your plugs..oil..etc etc,

any water in your oil..oil in your water.. all the small things, try figure out whats wrong. if its driveable..drive it till it breaks? lol..and then get a new engine! :]

my neon engine actually is working the best out of all the (lots and lots) of cars i have.. i had a 85 camaro, 88 firebird, 97SS, 97Z28 (sisters), 280Zx, dodge pickup.. etc etc.. and out of all of em, the neon's engine is in the best shape. i guess i got lucky? however, all the electronics on my car is f*ed up.
